Mainland China users can continue through the DUCHENG WeChat service account. Overseas teams can send the brand, model, fault code and site evidence through the website service form.
Choose the route that works at your site
The original service update introduced a fault-code query inside the DUCHENG WeChat service account. That route is intended for users in mainland China. It is not the only way to request support.
Mainland China: WeChat service account
Follow the DUCHENG Industrial service account and open the fault-code query from its service menu. Coverage varies by brand, product series and the current database version; always verify the result against the equipment manual and actual site condition.
Overseas: multilingual website request
If WeChat is unavailable, use the website service form. Send the equipment brand, full model, displayed fault code, clear cabinet or nameplate photos, a short description of what happened before the alarm, and your preferred contact method and time zone. The engineering team can then continue through an agreed channel.
Safety boundary
A fault code is a diagnostic lead, not permission to energize, bypass or dismantle equipment. Follow the manufacturer documentation and your site lockout/tagout procedure before any intervention.
